  // This mutating tree traversal works around a bug in the HLSL compiler optimizer with "pow" that
  // manifests under the following conditions:
  //
  // - If pow() has a literal exponent value
  // - ... and this value is integer or within 10e-6 of an integer
  // - ... and it is in {-4, -3, -2, 2, 3, 4, 5, 6, 7, 8}
  //
  // The workaround is to replace the pow with a series of multiplies.
  // See http://anglebug.com/851
